Abstract: PURPOSE: To freely and selectively enjoy a game by displaying an image on a front display via software, associating the pachinko (Japanese pinball game) balls shot on a machine board with the operation of a computer, and changing the image with an operation handle to play the game. CONSTITUTION: When lent pachinko balls P are put in an upper ball tray 5 and a game start button 3 is pushed, a detector 10 and a counting detector 16 are operated, a prescribed number of balls P for playing a game are received, and the image of the game is displayed on a display 2. In case of an 'air combat', for example, a friendly airplane in the image is freely maneuvered by an operation handle 7 to avoid the shooting from a hostile airplane. When a push button at the upper section of the operation handle 7 is pushed, a shot bullet is displayed on the image. Each time one bullet is shot, when the hostile bullet hits the friendly airplane, one or a proper number of pachinko balls P are taken in to the depth by a ball taking device 8. When a bullet hits the hostile airplane, a prescribed number of pachinko balls P are discharged into the tray 5 by a ball discharge device.  When the pachinko balls P are exhausted, the image display of the game is interrupted by the signal of the detector 10.

Title: Input signal discriminating circuit
Inventor: TATSUTA NORIHIRO
IPC: H04W4/00
Filed: 1983-10-19
Abstract: PURPOSE:To obtain a signal identifier capable of identifying sufficiently a signal from other input signals with simple constitution even if an input signal within a limited frequency is used by using the storage function of a flip-flop. CONSTITUTION:When a device is desired to be started, the 1st input signal is fed to a phase comparator 1 from a signal generator (not shown) and compared with a frequency of the 1st oscillating signal from a variable oscillator 2. When both the frequencies are coincident, the level of a terminal 12 goes to a low level and the flip-flop 5 is brought into standby state. Since a transistor 7 is turned off at the same time, the oscillating frequency of the variable oscillator 2 is decided by a capacitor 8 and a variable resistor 10, and the 2nd oscillation signal is fed to the said phase comparator 1. On the other hand, the 2nd input signal a different in frequency from that of the 1st input signal is fed to the comparator 1 afterward. When the both are coincident, a coincident signal is outputted, the flip-flop 5 in standby state is brought into the set state and an output to control the device (not shown) is transmitted.

Title: Liquid crystal electrooptical device
Inventor: KONUMA TOSHIMITSU
IPC: G02F1/139
Filed: 1992-06-30
Abstract: PURPOSE:To facilitate the orientation control of a liquid crystal and to increase a response speed and particularly a rising speed by forming liquid crystal oriented films subjected to rubbing treatments on a pair of substrates and confining the pretilt angle of the molecules of the liquid crystal to <=4 deg.. CONSTITUTION:A nematic liquid crystal 53 having positive anisotropy of a dielectric constant is interposed between a pair of the substrates 51 and 52. The liquid crystal oriented layers subjected to the rubbing treatments in opposite directions are formed on a pair of the substrates 51, 52. In addition, the pretilt angle of the molecules of the liquid crystal 53 is <=4 deg.. The magnitude of the polar group of the surface tension of the liquid crystal oriented layers is >=10 dyne/cm. Further, the magnitude of the surface tension of the liquid crystal oriented layers is >=40dyne/cm. Since the nematic liquid crystal of the positive anisotropy of the dielectric constant is used, the orientation control of the liquid crystal is extremely easy and since the layers like smectic liquid crystals are not formed, the orientation returns to the original orientation after external force is removed even if the orientation is once disturbed by the external force and, therefore, there is no need for heating the layers up to an isotropic phase or nematic phase.

Filed: 1983-10-19
Abstract: PURPOSE:To attain the control at a remote location by arranging a distribution function of an echo suppressor control signal near an analog echo suppressor at a remote location as a signal distributor so as to use one control line and one set of repeaters. CONSTITUTION:A central processing unit 9 transmits an echo suppressor disable order to a line controller 1 via a time division switch 10 and a digital multiplexer 8. The line controller 1 edits the said order for the purpose of control and the result is transmitted to a signal distributor at a remote location through a repeater 2. The signal distributor 3 selects a designated echo processor 4 and transmits a disable signal. The line controller 1 edits a connection end signal from the central processing unit 9 into an echo processor control signal and transmits it to the signal distributor 3 via the repeater 2 so as to enable the echo processor 4. Since the repeater 2 is used in common for lots of lines, the economical constitution of control lines is attained.
